Answer:
1.) How do solar thermal generators work?
D.) They use solar cells to covert sunlight directly into electricity
2.) Fossil fuel dependence has an impact on which of the following?
A.) the environment
3.) How much money does the United States lose each year due to the non-local resource trade deficit?
D.) 300 billion
Explanation:
In solar thermal generators. they depends solely on sun's energy for its energy generation and distribution. <em>The energy generation made use of solar cells which are cells joined together in series which helps in trapping the sun's energy and converting them into electric charges for its onward transmission to the circuit and battery leading to electricity. </em>
On the other-hand, over dependence on fossil fuel causes environmental issues like global warming due to gas flaring etc.
1.) To find the piston displacement, you have to find the volume of cylinder. The formula for volume is V = pi*r^2*h, where V = volume, r = radius, h = height
2.) V = pi*r^2h
= 3.14*2.25^2*4.5 (bore = diameter; hence r = diameter/2) (height = stroke)
= 3.14*5.06*4.5
= 71.4978 or 71.50
3.) Since the engine has 8 cylinders, multiply the piston displacement by 8
= 71.50*8
= 572
Therefore, the total piston displacement of an 8-cylinder engine is D. 572
Answer
The aspects and sectors of the U.S economy affected by regulations are;
• Allocative efficiency across sectors of economy
• Competition within industries
• Cost vs benefit in promoting public interests and goods
• Macroeconomic and employment sectors
Explanation
Regulations affect the manner national resources such as labor and capital are utilized in the production of goods and services. These regulations check whether the inputs are distributed to their desired uses. The regulation set the environment for new businesses to form and for the existing successful ones to grow and thrive. Regulations have an effect on both short term and long term economic growth in terms of employment during a recession period and in investment and innovation.
Answer: An effort to reduce the influence of the authority of church dignitaries.
Explanation:
The Reformation is a religious and social movement that originated in Germany, and very quickly spread to other countries. Martin Luther was the originator of the idea of Reformation, and this social movement had its representative in many other countries as well.
The demands and efforts of the reformers are diverse. Among other things, reformers also demanded a reduction in the influence of church dignitaries, including the pope himself. They emphasized the need to reject the material and to return to the original biblical principles. The authentic teaching of Jesus puts modesty at the forefront. Therefore, the reformers criticized the church itself, its splendor, and the wealth of high Catholic officials.
